imeaovl-:MENT IN wAoolNe, AND MACHINES Fon urs MANUFACTURE.

. Specification forming part of Letters Patent No. MQMLE 841i., dated June 24, 1873; application filed March 29, 1873.

To all whom it may concern: Y

Be it known that I, ANDREW CHAMBERS, of Providence, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in the Manufacture of Waddings, of which theA following is aspecification:

I propose` to manufacture weddings of old delaines, and other partcotton and part wool goods, by picking the stock into suiciently tineand soft particles to form a soft ne lap, which I make 'up in theordinary way, and then pass it directly from the machine in which it ismade through a bath composed of a solution of resin and caustic soda;also coloring matter, if I wish to color it, with which I saturate the-lap throughout and secure the ber so as to make as good and strong anarticle as the ordinary long ber will, and yet do/not injure the ber inrespect to the light, crispy nature which it is necessary for all goodwaddings to possess. The caustic soda les` sens the viscidity of theresin, so that While it does not prevent it from sticking the bertogether with sufficient tenacity, it prevents any apparent gumminess.The wool bers will also unite together, and with the cotton lber to someextent, by the fe'lting process.

The fabric may be made more or less line and dense according to theneness of the picking and the compression of the rolls. I also proposeto apply a dressing of plaster of Paris,

. or any other suitable substance to the surfaces of the vwadding as itpassesout of the bath, to glaze it and prevent it from sticking, bypassing it between a couple of boxes containing the plaster, and brushesfor throwingit on the wadding as it passes along.

Figure l is a longitudinal Vsectional elevation of a machine such as Iusefor making my new article of wadding; and Fig. 2 is a section of apiece of the wadding.

Similar letters of reference indicate lcorresponding parts.

A represents a picker, with a feeding-apron, B, feed-rollers C, screenwire-rol1ers D, and

a conducting case, E, such as are ordinarily used for picking, rening,and condensing 'the stock to form the lap, withA which picker andfeed-rollers I combine a fan, F, or beater to throw back any largepieces not sufciently picked to be Worked over. G represents a vat, andH carrying-rollers, which I combine with the above-described mechanismfor holding the solution for sticking the bers together, and carryingthe fabric through it as it comes fromthe delivery-rollers I, tocomplete the construction; and J, represents clsltrryingrollers forconducting the fabric from t e va When I wish to color the fabric I willmix the coloring matters with the sticking solution. I do not limitmyself to any particular sticking solution.` for any other which willanswer the purpose may be used.

K represents the plaster-boxes, between which I cause the waddin g topass by rollers L and M after passing out ofthe vat to receive thedressing of plaster of Paris'or any other suitable substance which isthrown upon it by revolving brushes N, through' openings 0 in the boxes,the brushes being operated in any suitable or approved way.

Having thus described my invention, I laim as new, and desire to secureby Letters Patent Y l. As a new article of manufacture, wad-v fdin gsmade of short ber stock, such as herein described, and saturated with lagummy solul tion, and also coated or glazed on .the surfaces,substantially as specified.

2. The combination of a vat G, and carry,

rollers H, with Amechanism for forming wadf dings, substantially asspecified.

3. The combination of boxes K, and brushes N, with the bath G,carrying-rollers H, and the lap mechanism, substantially as specified.

ANDREW CHAMBERS.
